Intermediate temperature fuel cell with a doped ceria–carbonate composite electrolyte

Effect of sintering temperature on surface morphology and electrical properties of samarium-doped ceria carbonate for solid oxide fuel cells

“…The surface area of the SDC powders obtained in the present study was higher than that of commercially available SDC powders [26] and previously reported powders [21,27,28]. A significant difference was observed in the specific surface area of the pure SDC powders after introducing (Li/Na) carbonate into the SDC matrix because of the increase in composite powder particle size.…”

“…This phenomenon results in the formation of a less porous electrolyte pellet with a low sintering temperature (550 °C) [23]. The SDCC composite surface area found in this study was higher than that in a previous report [21].…”

“…Xia et al [21] studied the influence of different surface properties of SDC powder prepared using the sol-gel (SG), glycine-nitrile (GN) and co-precipitation method on the performance of SDC-carbonate (SDCC) composite electrolyte. They found that the surface properties of SDC (powder structure, surface area and interface between SDC and carbonate phase) and electrolyte thickness significantly influence the performance of fuel cells.…”

A Novel Molten Oxide Fuel Cell Concept

“…have been examined to limit the ohmic loss through reducing the thickness of the electrolyte layer. Recently, more effective salt-ceriacomposite electrolytes are developed for hybrid molten carbonate/solid oxide fuel cells [2][3][4]. However, the CO 2 /O 2 gas mixture is needed as a cathode gas in the hybrid fuel cells.…”

Breakthrough fuel cell technology using ceria-based multi-functional nanocomposites

“…Moreover, combined MCFC and SOFC operation model is also possible. Li et al [39,82] proposed the ceria-carbonate (40 wt.%) composites as a hybrid-ionic transport electrolyte, which was operated by adding CO 2 at cathode side and achieved 1.7 W cm À2 at 650°C. It should be pointed out that …”
